Keaton still bats for Batman fans
Keaton took over directorial duties on the set of The Merry Gentleman when filmmaker Ron Lazzeretti's appendix burst and had to give up the project.
The actor thrilled cast and crew with his personable nature - and showed it extended to fans too.
Co-star Tom Bastounes explains, "One day we were filming in a park and there was little boy there and he had a makeshift Batman outfit on. It wasn't like a store-bought one. He made it at home.
"He had the pointy ears and the mask and he had a Batman symbol on his chest. Michael noticed him from across the street and walked over.
"Of course the mum noticed him right away and made a big fuss. The kid was about four or five. Michael signed the kid's cape and signed something for the mum. Then he brought them both to the set and they watched some of the shoot. He's very sweet that way.
"He's very generous with his time but you still have these pinch me moments, where you suddenly realise, 'Hey, I'm working with Batman.'"
